Police investigating the murder of 19-year-old Nikitta Grender have arrested a 26-year old man from the Newport area on suspicion of murder.
What first appeared to be a tragic death turned into a murder investigation when police revealed she had been stabbed twice.
50 officers are working on the case and they are still searching for the murder weapon.
The teenager was due to give birth in two weeks to a baby girl the couple had already named Kelsey-May.
Miss Grender’s parents, Paul and Marcia, paid tribute to their daughter and unborn granddaughter yesterday and spoke of their struggle to come to terms with the deaths.
CCTV footage from the area is also being scrutinised in the hope that it will offer a clue.
Superintendent Geoff Ronayne, who is leading the enquiry said: “We are continuing with the investigation today and we have many lines of enquiry to follow.
“We are continuing to appeal for information from the communities of Broadmead Park, Moorland Park and Pontfaen, specifically for private CCTV outside their addresses which could be really helpful to the investigation.
We also want any friends of Nikittas, anyone in her circle of friends or anyone who has been to her flat to contact us.
Superintendent Dave Johnson is urging people to continue in their help and co-operation.
He said: “We have received 58 calls from members of the public so far in the investigation and we would urge this to continue.
We understand there is strong feeling in the area but the best way to help police is to speak to us, not to speculate and give us as much information as possible so we can continue with the investigation.
We would urge people with any information or concerns to speak to officers at the scene,”
